>> thanks. >>> now, let's check in with susan rice, the lightening rod. president obama fiercely defended his u.n. ambassador today after republicans threatened to block her possible nomination for secretary of state. senators including john mccain and lindsey graham say what led americans surrounded the attacks in benghazi. >> if senator mccain and senator graham and others want to go after somebody, they should go after me. and i'm happy to have that discussion with them. but for them to go after the u.n. ambassador who had nothing to do with benghazi? and was simply making a presentation based on intelligence that she had received and to besmirch her reputation, it's outrageous. >> "outfront" tonight, rand paul of kentucky. he serves on the homeland security committee and senator paul, senator lindsey graham responded, i wanted to quote it. mr. president, don't think for one minute i don't hold you ultimately responsible for benghazi. i think you failed as commander in chief before, during and after the attack. i have no intention of promoting anyone w
